George is planning an experiment to see how fast different sized cans of soup can roll down a ramp in his kitchen. He will be rolling them down a ramp and them time how fast it take them to travel 1 meter after the ramp. Which of the following would count as the Dependant Variable of this experiment? a
The size of the Can
b
The velocity of the can after the ramp
c
The height of the ramp
d
The time it takes for the can to go down the ramp

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
